Widevine Decrypt Live Stream Player

[abaca20]

Hi,

Do you know if there's a way to decrypt live-stream Widevine-protected mpd's ?

I can download pasts fragments (like 5 min ago), i can decrypt them (mp4decrypt with key), but is it possible to watch a live-stream mpd and decrypt it with key ?

[jack_666]

have a look at https://github.com/xhlove/XstreamDL-CLI

Of course its possible to "watch a live stream mpd".
Why do we keep getting question after question about this ?

It makes no sense unless the real reason you want to decrypt a Live stream on the fly is to restream it live for others to view it live.

The common sense approach is to download the livestream, stop it when you're ready. Then decrypt it.

Re streaming live drm protected videos is a completely different approach. So which is it ?

Thanks, I'll take a look (with google translate...)

I want to decrypt a live-stream, I can't paste .mpd link in VLC because it's encrypted.
I have a .mpd link and I wanted to know if it was possible to decrypt it and view it in the same time.

I can already download and decrypt the livestream, but not in real-time.

If it's impossible it's okay, I was just asking (don't want to restream it for anybody)

Im not judging you or anyone else who keeps asking this. Far from it. If you are purely viewing it you can watch it in your browser. So maybe its just me, but I dont get your logic of wanting to feed an encrypted mpd into VLC player (?)

If its a half-hearted attempt to record it with the VLC record button, it uses ffmpeg so you are barking up the wrong tree there too.

Interesting thread.

And for decrypting widevine protected livestream (for a restream purpose), it's completely different compared to the methods used to decrypt VOD videos as we usually do ?

Actually, I use a live-tv service to watch live TV (I have a subscription, but this service has a free plan). But their app / website isn't working great (lags, etc). I wanted to watch it with VLC (more stable), or ffplay, but I can't decrypt and watch it in the same time.

I can still download past stream (like 5 min before) and decrypt it with mp4box, but it's not live-stream...

In fact, I don't know if there's a way to decrypt this live .mpd AND watch it in real-time
I said VLC because I just don't know if an alternative exists ...

Well, I can't decrypt a live-stream like a VOD because when we download a VOD, we have to download all fragments, they're muxed in a .mp4 file then we can decrypt it.

If i want to watch a live-stream, it can't download all fragments first because it's live, new fragments are coming every 3s so it can't be muxed in .mp4...

It works exactly like vod.
You get the initial segments and binary append upcoming segments till you want to cancel

Then decrypt it using mp4decrypt or ffmpeg


this is how it works for restreaming.

Thanks for the details. But I don't understand how can we go from an encrypted .mpd URL to a decrypted stream URL at the end (and not a local .mp4 file decrypted on your hard drive using mp4decrypt as we do for encrypted VOD)

They are first decrypted on VPS servers then restreamed to hls ( unprotected m3u8 )

If you have a live mpd with keys on you I can show you a demo.

You think i can set up something like this on my Windows ?

I have a live mpd with keys, can I send it to you in PM ? (don't want to get the key/mpd deleted...)

Nice. I'll PM you

I'm also interested a demo

[abaca20]

If someone knows how to do this, I'm interested...

If you just want to watch the live streams, use the keys and urls with a clearkey compatible app like tivimate or ott navigator, that's what I use in my tv.
If you want to make them available to other players/people you will need a paid server running a tool to convert them to unencrypted hls,(called wvtohls or mini_cs).

It's working with Tivimate & OTT Navigator, it's perfect for Android TV, it was exactly what I needed ! Thanks a lot !

have a live mpd with keys how to do this ?

[lfer94]

This chrome extension can play drm-protected live streams if you add "?&ck={"KID":"Key"}" at the end of the mpd. For example:

https://channel-tdn-cdn.blim.com/manifest.mpd?&ck={"4ae10c2357e250e088bb8a5ab044dd50":"e7f47e2b948e9222cf4d24b51881ec04"}

But first you must encode to base64 what is between curly braces using this website https://www.base64encode.org/

https://channel-tdn-cdn.blim.com/manifest.mpd?&ck=eyI0YWUxMGMyMzU3ZTI1MGUwODhiYjhhNWFiMDQ0ZGQ1MCI6ImU3ZjQ3ZTJiOTQ4ZTkyMjJjZjRkMjRiNTE4ODFlYzA0In0=

Then you just have to paste that link in the address bar and the stream will play.



Honestly, it's a bit useless because it doesn't work in external players like VLC, but maybe this method could be adapted to another tools

@lfer94

Thanks for sharing that tidbit

Did anyone solve this? Is there a working way/script that would continuously download new chunks listed in MPD file, decrypt them, join video and audio and finally make them available as HLS stream which is decrypted?

Of course there are many

Ffmpeg served over nginx is one example
There are already scripts to have a complete solution but I doubt seriously anyone going to just rock up and give you one
Also there are many variables to take into consideration when trying to restream something that's live

Play with ffplay:

Download and decrypt with ffmpeg:
ffmpeg -cenc_decryption_key 100b6c20940f779a4589152b57d2dacb -i https://bitmovin-a.akamaihd.net/content/art-of-motion_drm/mpds/11331.mpd -map 0:4 -map 0:5 -vcodec copy -acodec copy decrypted.mp4

[popmar88]

Thank you so much!!!!

-cenc_decryption_key was the missing flag... My ffmpeg version was not built with it. I downloaded the full latest build and it works like charm!!!!

What exactly did you download?
I get

Failed to set value '100b6c20940f779a4589152b57d2dacb' for option 'cenc_decryption_key': Option not found

and I downloaded the full latest build from gyan.dev
also just tried from BtbN

Yes, exactly that version and -cenc_decryption_key is there!

seems easy, but i want to play one live content , but if i try to play with exxtension or downlad i get only 40 seconds audio and video. i cant jump to the next segment here an example (st=1654072003~exp=1654072063). ffmpeg i presume will stop here. i can download another segment with actual data.
maybe i need to extract corect mpd for play? If someone can help me i will send it message on pm or on discord if possible.

What exactly are you trying to do
Download a live stream or convert to hls in real-time
